BUMIPER.

T0 aZZ wh0m z't may concern:

Be it known that I, GEORGE IIAINLEN, a citizen 0f the Unicec1 State3s residing in Philadelphia, Pennsylvania, have invented certain 1mprovements in Bumpers 01 which the fol1owing is a specification.

My invention r1altes t0 certain improvements in bumpers f0r vehic1es, especially those located at the front, 01 rear, 01 an automobi1e.

The object 0f my invention is to construct the bumper so that it 02m be readi1y applied to the frame 01 an automobile in such a manner that it will yield when struck, the supp0rt resisting the strain t0 Whi0h it is sub jecter1.

In the accompanying drawings:

Fig. 1 is a side view 01' my improved bnmper secured to the r"ront frame 01 an automobile;

Fig. 2 is a front view 01 one encl of the b ump er Fig. 3 is a sectiona1 view 011 the 1ine 83, Fig. 1;

Fig. 4 is a detached perspective, view 01 the bezrring plate that is sscured t0 the automobile fmme, anc1 Fig. 5 is a view 01 a modification.

Referring to the drawings, 1 is one 01 the side frames 01 an automobile mac1e in the form 01 a channe1, having a solic1 enc1 2 in which is the opening f0r the assage 0f the b01t 3, W111C11 secures the front spring 4 t0 the frarne. The 130115 3 may be made in any suitable manner and is usually supp1ied with a assage f01 lubricant. The two side frames are spaced apart and the bumper bar 5 ex tends across the front 0f the frame anc1 is supported at each side frame by my improved structure.

6 designates a bearing platze, which is hollow 0n the under side to form flanges that rest upon the frame. At one sic1e 01 the plate 6 is a depending arm 7, preferab1y integral with the p1ate. This arm has an opening 8 f0r the assage of the spring b01t Staking the p1ace 01: the usua1 W2\S1181. On the opposite side of the p1ate 6 is a projecting lug 9, which has an opening therein for the passage 01 a hooked bolt 10 that passes under the flamme. On the holt 10 is a nut 11. On turning the nut, the holt is drawn tightly again5t the frame, drawing ehe bearing plate 6 to its seat on the frame. This construction makes a rigid fastening without perforating the frame at the end.

Serial 1\T0. 695,543.

Projecting from the upper surface 0fthe bearing plate are two bearings 12, perforated for the passage 01 a pivot b01t 13, having a nnt 14. Mounted 0n the holt 13 is a twoarmed 1ever bracket 15. One arm 16 01 the bracket has a clamp ring 17, W111C-11 encircles the bumper bar 5. The ring is sp1it, as shown in Fig. 1 and has 1ugs t1nough which a c1amp screw 19 extends, which draws the ring tightly upon the bmnper bar 10 hold it against longitudinal. movement. The 0ther arm 20 01 "che bracket 15 is shaped t0 provide a space for the yie1ding member 21 which, in the present instance, is a s01id rubber ball. In some cases, however, a metallic spring may be substitutec1 10r the ball. The end 01 the arm 20 is perforatecl f0r the Passage of a bolt 22, which extends through the 102111 and through a perforation in the bearing p1ate.

The head 28 of the holt 22 is locatec1 in the cavity in the bearing plate between the p1ate and the frame. A nut 24 is secured t0 the opposite end 01 the holt and rests upon the arm 01 the bracket. This construction avoids drilling the frame. The bolt 22 may extend through the flanges 0f the frame as shown in Fig. 5 if 1i'ound desirable.

There are two supports for the bumper bar. One supporr is mounted in each side frame 01 the automobile. VVhen the bumper strikes an object it yields sufiiciently t0 cushion the b1ow. The brackets turn on their p-ivots, anc1 the ball 21 is compressed. T119 arm 0f the bracket rides 011 the holt 22. The spring b01t 3 and the hooked bo1t 10 resist the pressure and hold the bearing p1ate firm1y t0 its seat.

The improved bumper 1S neat in appearance and can be readily applied to the frame 0f an automobile without drilling the frame .for the securing means.
